Hello

I am unable to get the horizontal Housemenu to display in Firefox, any suggestions.

I am using Dnn 4.3.5, Housemenu v 1.4 

This is my housemenu setting:

 <dnn:HOUSEMENU runat="server" id="dnnHOUSEMENU" Scope="-1" IsRecursive="True" Orientation="H" ShowAdmin="True" Mode="D" CssElementId="HouseMenuNav" /></div>
